The Ultra High Performance level is the only OCI Block Volume performance level that can meet the requirement of at least 105 IOPS/GB and 100,000 IOPS per volume. The Ultra High Performance level is recommended for workloads with the highest I/O requirements, requiring the best possible performance. With this option, you can purchase between 30 – 120 VPUs (volume performance units) per GB/month. The VPUs determine the baseline performance of the volume, as well as the maximum burst performance. The Ultra High Performance level offers the following performance characteristics: 1

• Baseline IOPS/GB: 75
• Maximum IOPS/GB: 300
• Maximum IOPS per volume: 480,000
• Baseline throughput/GB: 0.6 MB/s
• Maximum throughput/GB: 2.4 MB/s
• Maximum throughput per volume: 3,680 MB/s

To achieve the requirement of at least 105 IOPS/GB, you need to purchase at least 45 VPUs/GB. To achieve the requirement of 100,000 IOPS per volume, you need to have a volume size of at least 334 GB. Therefore, the Ultra High Performance level can satisfy both requirements with a minimum volume size of 334 GB and a minimum VPUs/GB of 45.

The other performance levels (Balanced, Higher Performance, and Lower Cost) cannot meet the requirement of at least 105 IOPS/GB and 100,000 IOPS per volume. The Balanced level offers 10 VPUs/GB, with a baseline of 60 IOPS/GB and a maximum of 75 IOPS/GB. The Higher Performance level offers 20 VPUs/GB, with a baseline of 75 IOPS/GB and a maximum of 150 IOPS/GB. The Lower Cost level offers 2 VPUs/GB, with a baseline of 2 IOPS/GB and a maximum of 10 IOPS/GB. None of these levels can provide the required performance for the workload1

What Is IaaS?

Infrastructure as a service (IaaS) is a type of cloud service model in which computing resources are hosted in the cloud. Businesses can use the IaaS model to shift some or all of their use of on-premises or colocated data center infrastructure to the cloud, where it is owned and managed by a cloud provider. These infrastructure elements can include compute, network, and storage hardware as well as other components and software.

In the IaaS model, the cloud provider owns and operates the hardware and software and also owns or leases the data center. When you have an IaaS solution, you rent the resources like compute or storage, provision them when needed, and pay for the resources your organization consumes. For some resources such as compute, you’ll pay for the resources you use. For others such as storage, you’ll pay for capacity.

How Does IaaS Work?

In a typical IaaS model, a business—which can be of any size—consumes services like compute, storage, and databases from a cloud provider. The cloud provider offers those services by hosting hardware and software in the cloud. The business will no longer need to purchase and manage its own equipment, or space to host the equipment, and the cost will shift to a pay-as-you-go model. When the business needs less, it pays for less. And when it grows, it can provision additional computing resources and other technologies in minutes.

In contrast, in a traditional on-premises scenario, a business manages and maintains its own data center. The business must invest in servers, storage, software, and other technologies, and hire an IT staff or contractors to purchase, manage, and upgrade all the equipment and licenses. The data center has to be built to meet peak demand, even though sometimes workloads decline and those resources stand idle. Conversely, if the business grows quickly, the IT department might struggle to keep up.

The primary use case for using Web Application Firewall (WAF) in OCI is to filter malicious web traffic and protect internet-facing and internal applications from attacks. WAF is a cloud-based, PCI-compliant, global web application firewall service that monitors and controls access to web applications based on predefined rules and threat intelligence. WAF can block common web application attacks such as cross-site scripting (XSS), SQL injection, remote file inclusion, etc., as well as bot traffic, geographic restrictions, rate limiting, etc. WAF can protect any internet-facing endpoint or internal application by attaching WAF policies to enforcement points such as load balancers or web application domain names10

Setting up your application across multiple fault domains is a way to configure high availability for an application in an OCI region with a single availability domain. A fault domain is a logical grouping of hardware and infrastructure within an availability domain that is designed to be isolated from failures in other fault domains. Fault domains let you distribute your instances so that they are not on the same physical hardware within a single availability domain. This reduces the impact of hardware failures, power outages, or network issues on your application availability and performance. Each availability domain has three fault domains, regardless of the number of availability domains in a region1

Oracle Data Safe is a unified control center for your Oracle databases which helps you understand the sensitivity of your data, evaluate risks to data, mask sensitive data, implement and monitor security controls, assess user security, monitor user activity, and address data security compliance requirements.

Whether you’re using an Autonomous Database or an Oracle DB system, Oracle Data Safe delivers essential data security capabilities as a service on Oracle Cloud Infrastructure.

In Oracle Cloud Infrastructure, you can set up email alerts to receive notifications when budget thresholds are reached. Email alerts are sent to users who are subscribed to a budget alert rule, which specifies the percentage or amount of budget consumption that triggers the alert. Email alerts help users monitor and control their cloud spending.
